Abstract Communication satellites of Japan, CS-2a and CS-2b were launched in 1983. Each satellite has 6 Ka-band transponders and 2 C-band transponders. Operational users of public or governmental organizations are using CS-2s. In addition to these operational users, CS-2 Pilot Program participants are using CS-2s for preoperational experiment in Ka-band. More than 50 earth stations of Ka-band are utilizing CS-2s in operational use. Configuration of the operational use are back-up link to their terrestrial lines in an emergency or tentative transmission link in case of disaster or event. Satellite business communication services using small antenna started recently. 32 earth stations of 1 to 5 meter antenna are used in the Pilot Program. Some results of experiments in Pilot Program were obtained.
